What are the excellent properties of nickel titanium alloy?

The core excellent properties of nickel titanium alloy are shape memory effect and superelasticity, as well as good biocompatibility and corrosion resistance, which make it widely used in multiple fields.

Nickel titanium alloy is a special alloy that can automatically restore its plastic deformation at a certain temperature.

In addition to its unique shape memory function, nitinol also has excellent properties such as wear resistance, corrosion resistance, high damping and superelasticity.

Its specific excellent performance can be divided into the following categories:

-Unique mechanical properties
-Shape memory effect: After plastic deformation occurs at low temperatures, materials only need to be heated to a specific "transition temperature" to fully restore their original shape before deformation, and the restoration process is stable and reproducible.
-Super elasticity (pseudo elasticity): When subjected to external forces at room temperature, it can produce elastic deformation far exceeding that of ordinary metals (up to 8% -10%), and can instantly restore its original state after the external force is removed, with excellent fatigue resistance.
-Good biocompatibility: It is not easy to cause immune rejection reactions in the human body and can form a good interface with human tissues (such as bones and blood vessels). It is a key material for making medical devices such as heart stents and orthopedic implants.
-Excellent corrosion resistance: The surface is prone to forming a dense oxide film, which can resist erosion from body fluids, seawater, acidic and alkaline environments, and has a long service life. It is suitable for medical, marine engineering and other scenarios.
-Other auxiliary properties: It has suitable conductivity and thermal conductivity, good processing performance, and can be made into silk, pipe, plate, and complex shaped components through various processes to meet different application needs.
